###### Two Dimensional Array - Question 3

In this question, we will see how to input numbers in a 3X3 integer matrix (2d array) and print the largest and smallest number from it in C programming. To know more about two dimensional array click on the two dimensional array lesson.

**Q3)** Write a program in C to input numbers in a 3X3 integer matrix (2d array) and print the largest and smallest number from it.

#### Program

```
#include <stdio.h>
#include <conio.h>
int main()
{
int a[3][3], r,c,lg=0,sm=0;
printf("Enter 9 numbers\n");
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
scanf("%d",&a[r][c]);
if(r==0 && c==0)
{
lg=a[r][c];
sm=a[r][c];
}
else if(a[r][c]>lg)
{
lg=a[r][c];
}
else if(a[r][c]<sm)
{
sm=a[r][c];
}
}
}
printf("Largest number = %d\n",lg);
printf("Smallest number = %d",sm);
return 0;
}
```

#### Output

Enter 9 numbers 63 24 15 3 75 2 19 31 42 Largest number = 75 Smallest number = 2
